Discussion

Plants recently discovered in the southern Appalachian Mountains (Georgia, North Carolina, and Virginia) have staminate spikes similar to those of Carex deflexa var. boottii, averaging larger than those of var. deflexa. They also tend to produce basal spikes more consistently than do the northern plants.
